FLU, FEVER, VOMITING, DIARRHEA: 1  If your symptoms include fever and / or vomiting, contact your doctor.

GI Motitility In the Stomach. 1  Two types of movement (motility) occur in the stomach: peristalsis and segmentation (mixing). 2  The contractions occur about every 20 seconds and proceed from the body of the stomach toward the pyloric sphincter. 3  About 20% of the contractions in the stomach are peristaltic waves.
Peristalsis in the smooth muscle of the esophagus is dependent on both central and peripheral mechanisms. The central mechanism involves patterned activation of the preganglionic neurons in the dorsal motor nucleus of the vagus that project onto inhibitory and excitatory neurons in the esophageal myenteric plexus.
